Silicone breast forms are made of medical-grade silicone, providing a realistic, natural, and lightweight feel. They are ultra-soft, safe, and feature an elastic texture that quickly regains shape after handling. Weight: 100g per piece. The axisymmetric triangle shape is designed to match the natural weight and curves of the chest. It features a deep concave backside for breathability, making it especially suitable for individuals who have undergone complete mastectomy or lumpectomy. Ideal for women with breast defects due to mastectomy or breast cancer. Also appropriate for those with flat chests, as well as for cross-dressing, transgender use, cosplay, and similar applications. Can be worn inside a bra pocket or adhered directly to the body using special adhesive. Reusable and easy to clean: rinse with mild soap after each use. Avoid contact with sharp objects such as scissors, needles, or sharp nails. Store in a box or bag when not in use and keep away from direct sunlight.
